RM-2000 CBM SYMCOM Remote Monitoring Device
Model RM-2000 CBM
The RM-2000 CBM (Coal Bed Methane) Special/777combination optimizes gas production from coal bed methane wells while protecting the submersible pump. The 777 provides unmatched pump protection while the RM-2000 CBM Special cycles the pump based on pressure measurements from one or two 4-20mA pressure transducers.
The first transducer measures down-hole pressure while an optional second transducer can be used to measure annulus pressure (gas pressure). The second transducer corrects head measurements caused by high annulus pressure. The pump is started when the maximum head setpoint is crossed and stopped when the minimum head setpoint is crossed. The feet-of-head is displayed in real time with the turn-on and turn-off head setpoints. This system is compatible with a wide range of 4-20mA pressure transducers.
A built-in, rapid-cycle timer prevents overcycling the pump if the water level recovers too quickly. The rapid-cycle timer can be used to delay pump starts on wells with high annulus pressure when the annulus transducer is not used. A real-time display shows the remaining time before the pump can automatically restart.
